IMPROVEMENT IN HYDRULIC TURNPIPES.

The Schedule referred to in these Letters Patent and making part of the same.

tube with nozzle attached, to be used for delivering.

a stream of -water in hydraulicmi ning.

My improvements consist--A First, in constructing the pipe -near the nozzle in such-formed sections that, when. united together, it will be of a convenient shape, not only for handling, but also forvdelivering the water; and

Secondly, in the manner of relieving the strain upon the moving joints, in order' that the nozzle may be easily turned about for changing the direction ot" the stream of water.

In order to better illustrate and explain my invention', reference is had to the accompanying drawing vforming a part of this speoicatiou, `in which- A is the lower section of the turnpipe, and is connected with the main pipe which conveysthe water to the mine. This section is curved as shown, and has the plate a cast with it, which is provided with screw-holes, in order to secure it in the proper position upon the timber' B.

The section C is also curved, and is secured upon the upward projecting end of the section A by means of some suitable loosely-moving water-tight joint, the two sections when united forming an S-shaped pipe, thel upper section of which is capable of being turned so as to present the end in any desired direction.

To the end of the section C is secured a short section of pipe, D, by means of flanges b or other suita` ble device, and to this is secured a short hose, E. v

The nozzle F is secured to the opposite end of .the hose, and in delivering a stream, when it4 is desired only to vary the direction slightly, the flexibility of j the hose will be sucient to allow the nozzle to be directed without changing the position of the turnpipe.

Cast upon the upper horizontal surface of the sec- I tion A is a plate, d, to which is strongly secured, hy

suitable means, a curved har or arm, G. The upper.

end ofv this har is provided with a screw-hole, tlirough which a screw, f, passes, lthe lower end of which 'is hollowed so as to hear upon the conical projection c. rIhis conical projection is cast vupon the section C, di-

rectly in aline with thecenter ofthe circular moving water-tight joint which connects the two pipes, A O. This screw serves to relieve the pressure upon the -joint when the vpipe is carrying a stream, in order tov allow the section C to' be readily turned as desired. rJ.his is necessary, as the immense pressure of the water, which is frequently two hundred and fty pounds to the square inch, would otherwise seal the joint so strongly that it would he almost impossible to move it, but by turning the screw down this pressure is counteracted, and the pipe moves between the water and pivot.

Upon `the flange b is cast a lug or projection, 1i., through which there is a hole suflciently large to admit the end of an iron bar to aid in turning the pipe into position. l

What Iclaim, and desire to secure by Lcters Pat,- ent, is-

1. The combination .of the bent pipes Land C, connected by a loose joint with the iiexible pipe E and nozzle-F, when arranged to operate substantially as described.

2. In combination with a bent revolving pipe, C,

-the standard G, screw j, and projection c, substan-A tially as 'and for thep'urpose specified.

In witness whereof IV have hereunto set my hand and seal.
